David Gonlag of Kenmore says he didn't feel like himself and that's what prompted him to visit his primary care physician and then a neurologist.
"It got to the point I'd go into meetings come out and I couldn't remember things," Gonlag told 7 Eyewitness News.
At just 55 years old this accountant, father, and husband was diagnosed with dementia.
"In a way I was sort of relieved because I didn't know what was wrong but I knew something was wrong," Gonlag said.
It's a story similar to that of teen idol David Cassidy who recently revealed his own battle with dementia at the age of 66.
Dr. Maurice Hourihane is with Dent Neurologic in Orchard Park. He says there are noticeable clues that something may be wrong.
"If you're giving out your social over the phone to telemarketers. . . looking at the check book and being unable to balance it."
Other signs? Driving becoming erratic and mixing up medications.
Dr. Hourihane says there is more support and awareness than ever before including support groups and information offered through the Alzeheimer's Association.
